Your ghc is your native (amd64) compiler (provided by debian as a
package)? If so, then this is not supported. You need to compile ghc
from source and configure it as a cross-compiler. Another problem is
that armv7-m supports only thumb-2 isns while GHC HEAD IIRC switched to
arm isns solely. The last problem may be lack of support for armv7-m in
GHC's RTS (runtime) or for your (probably?) RTOS which you run on armv7-m?
